Long, soft curls and waves look classic and fresh at the same time — just check out Audrina Patridge's hair here. But raise your hand if you've ever spent time meticulously styling your hair, only to watch the curls go limp within an hour. Annoying. But stylist Dean Banowetz, whom you may know from the InStyler, has an easy fix.

"After you’re done curling the hair, roll the hair back up and pin it with a clip," he says. "That's really essential, because then the hair can cool properly in that formation. While it's cooling, finish your makeup or finish doing whatever else it is you need to do. If you want the curl to loosen out, you can just let it hang."

Be sure to use hair spray to set the curls. (Banowetz recommends Tre Milano Shine Spray.) Then, watch your waves stay all day long. Easy!
